I'm not Strol jr. fan but 20s is nothing considering a street circuit and where he started from. The guy probably did the most he could have and he's done well here before so it is fine where he finished. He should have finished higher.. yup and it was his own fault he didn't but give the guy a bit of credit to the gap and reasoning. He did better then a lot of other guys out there.. HE still cost the team valuable points and places but he made the most of his outcomes.
Starting higher up the grid is not a guarantee of finishing there.
